Finally, my DISCUZ cannot connect to your server. maybe your server is on the cloud platform of the backend forum of the firewall ~ _ PHP Tutorial

Finally, my DISCUZ cannot connect to your server. maybe your server is on the cloud platform of the backend forum of the firewall ~. Cause: I deleted most of the source files of the Forum by mistake due to a backup problem a few days ago, so I downloaded the source code again and passed it to the space. Then the problem came. I closed the vertical and horizontal search and prompted that the cause could not be solved: due to a backup task a few days ago, I deleted most of the Forum source files by mistake, so I downloaded the source code again and passed it to the space.

Then the problem arises. when I close the vertical and horizontal search, the system prompts "you cannot connect to your server, maybe your server is in the firewall backend", and the vertical and horizontal search page displays "operation failed "~~

After a while in the morning at the DISCUZ official forum, I checked it with my own detection tool and reported an error "you cannot connect to your server, maybe your server is at the backend of the firewall ".

According to the post, it may be a problem of communication between the host and the cloud platform. check whether the space service provider has enabled the firewall. So I asked the service provider to exclude it. The final check found that the permission for uploading new files was 777, because it was previously installed, and the installer did not verify the permission for files. Therefore, the permission is set to 755 again.

Check again. The error is successful.

So I tried to close the vertical and horizontal search again, or I was prompted that the operation failed. why?

So I want to create a new site in the space and migrate the configuration file directly to see if there is such an exception in the new site. After I have done all the necessary work, after activating the cloud platform, he prompts me that the KEY is incorrect ..

So I considered whether my new source file is a KEY. Can I use the cloud platform> Site Information> KEY replacement function to try it?

After the function is used, the prompt "cannot connect to your server, your server may be at the backend of the firewall" is disabled, and the problem of "Operation failed" is solved by setting the vertical search ~~~

Haha, we still need to analyze the problem to get the result!
